SPECIFICATION forming part of Letters Patent No. 354,647, dated December 21, 1886.

Application filed September 9, 1886. Serial No. 213,131. (No model.)

T0 aZZ whom it may concern.-

Be it known that 1, CHARLES P. McWANn, a citizen of the United States, residing at Wytheville, in the county of WVythe and State of Virginia, have invented a new and useful Improvement in Plows, of which the following is a specification.

My invention relates to an improvementin plows; and it consists in the combination, with a plow, of a supporting-wheel in rear of the share, whereby the draft of the plow may be lightened and the plow caused to be run either shallow or deep; and my invention further consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a side elevation of a plow embodying myimprovements, a portion of the mold-board being broken away,so as to disclose the supporting-wheel. Fig. 2 is a rear elevation of the same Fig. 3 is a de: tailed elevation of the landside of aleft-handed plow, showing the adjustable block attached thereto, the supporting-wheel being indicated by a dotted circle. Fig. 4 is a vertical transverse sectional view taken on the line a; w of Fig. 3. Fig. 5 is a detailed perspective view of the slide.

A represents a plow of the usual construction, of which Bis thelandside and G the moldboard.

On the inner side of the landside, at the rear end thereof, is formed a horizontal tongue, D, the sides of which areinclined to form an acute angle.

E represents a bolt, which projects inwardly from the landside, and passes through an opening which is made therein and enters a vertical slot, F, which is made in a block, G. The said block rests against the inner side of the rear end of the landside, and is provided on one side with a series of horizontal grooves, H,

which are adapted to receive the tongue D. The said grooves H are arranged one above the other, and it will be readily understood that the block G is thereby adapted to be adjusted vertically on the landside. A'nut, I, is

screwed onto the inner end of the bolt E, and bears against the outer side of the block G, thereby firmly clamping the latter to the landside.

From the inner side of the block G extends a horizontal sleeve, K, on which is journaled a supporting wheel or roller, L. A bolt, M,

extends through the central bore of the sleeve K, and on the inner end of the said bolt is fitted a washer, N, which bears against the end of the sleeve and prevents the wheel from becoming moved therefrom. A nut,O,is screwed on the inner threaded end of the bolt N, and secures the washer in place thereon.

From the rear upper side of the block G projects an inclined arm, I, which is arranged on the rear side of the wheel L. g

It represents a scraper, which is made of steel, and is sharpened at one edge,,and the said scraper is provided with a slot, S.

T represents a clamping-bolt.

The scraper is placed on the lower rear side of the inclined arm P, and the clamping-bolt T extends through the slot S and through an opening which is made in the arm P, and is provided with a nut, T, that is screwed onto its threaded endzand bears against the upper side of the inclined arm. This permits the scraper to be adj usted'toward or from the pe riphery of the wheel L.

From the foregoing description it will be readily understood that the wheel L is vertically adjustable in rear of the plow, and may be raised or lowered at will. The function of the said wheel is to bear'on the bottom of the furrow on the inner side of the landside, so as to raise the heel or sole of the landside, and thus greatly lighten the draft of the plow.

By adjusting the supporting-wheel up or down the plow may be caused to run in the ground at any desired depth. The wheel is also of great utility to the plowrnan in other ways. In the event that the plow reaches an obstruction which it is necessary to clear, the plowman grasps the handle and raises the point of the plow and throws its weight entirely upon the supporting-wheel L, when theplow may be easily rolled over the obstruction. Another advantage gained by employing thev supportingwheel in rear of the plow is that the plow may be readily turned at the end of the furrow by raising the point and causing it to be entirely supported by the wheel, thus rendering the plow exceedingly easy to handle, and.

greatly lessening the labor of the plowman.

In certain conditions and qualities of soil a wheel cannot be employed to advantagein connection with the plow. I therefore provide a slide, U, having a vertical arm, V, provided with a vertical slot, V. On the inner side of the arm V, at the lower end thereof, are a series of horizontal grooves,W,corresponding to the grooves of the plate G. hen the land is very rough or wet, the plate G, with the supporting-wheel, is detached from the landside of the plow, and the slide or runner is attached to the landside in lieu thereof and in the same manner. This slide or runner is also vertically movable on the rear end of the plow, and is adapted to slide freely and easily over the bottom of the furrow in wet or rough land.

I do not desire to limit myself to the precise construction and arrangement of the devices herein described, as it is evident that modifications may be made therein without departing from the spirit of my invention.

Having thus described my invention, I olaim- 1. The combination, with the plow having the rearward-extended landsideprovided with the horizontal tongue D, of the block G,b0lted to the landside and adapted to carry the wheel or shoe, and having the series of horizontal grooves for the reception of the tongue D, whereby the said block is vertically adj ustable on the landside, substantially as described.

2, The combination, with the plow, of the vertically-adj ustable block attached thereto in rear of the share, the supporting-wheel journaled on the block and adapted to run in the furrow, the arm extending from the block,and the scraper attached to the said arm on the rear side of the wheel, vsubstantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in presence of two witnesses.
